Answer:
The sound intensity is about 101.9 dB
Step-by-step explanation:
Sound intensity is the amount of sound energy per unit area.
The intensity of the dog bark is 10⁻⁵ W/in². The intensity of sound in decibels is given by:
I = 10⁻⁵ W/in² = 0.0155 W/m²
Therefore:
The sound intensity is about 101.9 dB
Answer:
3rd answer
Step-by-step explanation:
If you look at the translation, each point is moved 6 to the right on the X axis, and down 4 on the y- axis. so, therefore it should be (6,-4)
Answer:
CH = 22°
Step-by-step explanation:
We know that Arc AC and Arc CH both equal to 180°, therefore we can say;
AC + CH = 180°
158 + CH = 180°
CH = 180 - 158
CH = 22°
Hope this helps!
X would be 39
Add the two angles to get 90+51 =141
Then subtract 180 from 141 to get 39
Answer:
Principal = $500
Interest = $37.50
Rate = 0.025 = 2.5%
Time = 3 years
Step-by-step explanation:
The formula for simple interest is I = PRT ÷ 100
Casandra's equation = I= 500(0.025)(3)=$37.50
Principal = $500
Interest = $37.50
Rate = 0.025 = 2.5%
Time = 3 years
